9/14:Arizona Cardinals running back David Johnson (back) practiced in full on Friday and labeled himself "100 percent" after being limited earlier in the week. All signs are pointing toward him being active against the Rams in Week 2. As long as Johnson is on the field on game days, he'll be a must-start for fantasy owners. Keep him in your lineups.--Keith Hernandez - RotoBallerSource: ESPN.com - Josh Weinfuss
